Change Order Approval Workflow
This procedure defines the mandatory workflow for initiating, reviewing, approving, and implementing change orders within manufacturing operations to maintain production integrity, cost control, and regulatory compliance.
The Change Order Approval Workflow establishes a standardized, auditable process for managing all engineering and operational changes that impact product specifications, manufacturing processes, tooling, materials, or quality standards. This procedure ensures every change is properly scoped, risk-assessed, costed, and authorized before implementation, minimizing disruptions to production and preventing non-conformances. The workflow integrates with existing ERP and quality management systems to maintain a complete revision history and enable root-cause analysis when deviations occur. All personnel involved in initiating, reviewing, or approving change orders must adhere to the directives defined herein.
This workflow applies to all change orders submitted for production processes, bill of materials (BOM) revisions, tooling and fixture modifications, supplier-sourced component changes, quality control plan updates, and health, safety, or environmental control adjustments. It is mandatory for all manufacturing, engineering, supply chain, and quality assurance personnel at every facility. Contractors, temporary staff, and third-party integrators working on-site must also comply when their activities affect production specifications or controlled documents. Exclusions are limited to administrative corrections (e.g., typographical fixes) that do not alter form, fit, function, or regulatory compliance.
- All change orders must be documented using the approved digital form (CO-001) and submitted via the designated ERP module or paper equivalent. Incomplete submissions are automatically rejected within 24 hours.
- Every change order must include a risk assessment (severity × likelihood) signed by a qualified engineer. Changes scoring ≥12 on the 5×5 matrix require pre-approval from the Plant Manager before the review committee convenes.
- No change order may be implemented without written approval from at least two of the following: Operations Manager, Quality Manager, or Engineering Lead. Changes affecting regulatory compliance require explicit sign-off from the Compliance Officer.
- A change order review committee must convene within five business days of submission. The committee comprises representatives from operations, engineering, quality, supply chain, and HSE. Decisions require majority vote; tie-breaking authority rests with the Operations Manager.
- Approved change orders must be implemented within 30 calendar days unless a variance is granted by the review committee. All affected documentation (SOPs, work instructions, control plans) must be updated within five days of implementation.
- A post-implementation review must be conducted 14 days after implementation to verify effectiveness and capture lessons learned. Findings are recorded in the change log and used to update the risk register and FMEA documents.
- Change Requestor (Initiator): Completes the change order form, provides supporting data (drawings, specs, cost estimates), and presents the proposal to the review committee. Responsible for ensuring the accuracy and completeness of the submission.
- Engineering Lead: Reviews technical feasibility, performs risk assessment, and approves or rejects from an engineering standpoint. Ensures all design changes comply with applicable codes and standards.
- Quality Manager: Evaluates impact on quality control plans, inspection criteria, and regulatory requirements. Approves only when verification and validation activities are defined and resourced.
- Operations Manager: Chairs the change order review committee, resolves tie votes, and has final approval authority for changes below the Plant Manager threshold. Monitors implementation timelines and escalation procedures.
- Supply Chain Lead: Assesses supplier impact, lead time implications, and inventory disposition. Approves changes that affect purchased parts or subcontractor scope.
- Plant Manager: Provides final sign-off for high-risk changes (risk score ≥12) and changes exceeding a capital threshold of $50,000. Delegates authority to the Operations Manager for routine changes.
